Kwa-Zulu Natal, South Africa – Heavy rains and storms in the province have caused havoc with roads and railway lines flooded, landslides and tornadoes. Beaches in Durban have been closed while emergency services have battled to keep up with rescue services. Across the high altitudes, snowfalls have been seen across large areas of the Drakensburg.

Hawaii – Oahu reported heavy rainfall from Tropical Storm Darby, and officials said dozens called for help as their homes were surrounded by water.

Moscow, Russia – Moscow Mayor Sergei Sobyanin has been mocked online after extraordinary flooding wreaked havoc in the Russian capital and briefly submerged a street next to the Kremlin in knee-deep water. City authorities said the flooding on July 22 was the result of a freak rainfall. During the heavy downpour, social networks were inundated with pictures of cars driving through what looked like rivers and lakes that had formed on iconic central Moscow streets.

Disease

Haiti Cholera Count

Through July 9, Haiti has reported 21,661 suspected cholera cases and 200 related deaths. In all of 2015, the island country saw 36,644 cholera cases and 321 deaths. Since the cholera outbreak began in October 2010, months after the Jan. 12, 2010 earthquake, 776,633 cases and 9,163 deaths have been recorded. And this cumulative number may be lowballing it, according to a recent study in the journal, Emerging Infectious Diseases, which reveals from house-to-house surveys in four communities that there were an estimated nearly three times more cholera deaths in the first six months of the epidemic than officially recorded.

Prior to Oct. 2010, Haiti had not seen a cholera outbreak in a century.

In neighbouring Dominican Republic, 894 cholera cases and 17 deaths have been reported this year to date.

Zika Virus Epidemic in Colombia Over

Colombian health officials declared on Monday that the worst of a Zika outbreak in the Andean nation had passed just 10 months after its arrival, raising questions about how the virus is affecting parts of Latin America differently.

Vice Health Minister Fernando Ruiz told journalists that the number of infections in Colombia has been falling by 600 cases a week. While Zika is still circulating in the country, Colombia considers the drop-off sufficient to say it has moved into an endemic phase from the epidemic phase. Colombia has reported nearly 100,000 cases of infection, with 21 cases of Zika-related microcephaly.

Wildfires

Wildfires – California, USA

A massive wildfire destroyed at least 18 homes and threatened 1,500 more as flames churned through tinder-dry canyons north of Los Angeles. The fire on Sunday had gained ferocious new power two days after it broke out, sending so much smoke in the air that planes making drops on it had to be grounded for part of the afternoon.

About 480km up the coast, crews were battling another fire spanning more than 44 square kilometres that destroyed six homes on Sunday and forced evacuations outside the scenic Big Sur region. About 900 firefighters were battling the blaze in temperatures exceeding 41 degrees Celsius, aided by 28 water-dropping helicopters and eight fixed-winged aircraft.

Wildfires – Utah, USA

Battling triple-digit temperatures, crews were close to completing containment lines around a nearly 15,000-acre wildfire on tinder-dry rangelands of the Great Salt Lake’s Antelope Island.

Crews adopted a defensive stance at the lightning-caused Lower Ebbs Fire, which had burned 5,000 acres of sage, pinyon and juniper about 4 miles southwest of the Millard County town of Scipio. Fire Information officer Adam Solt said the three-day-old blaze was 15 percent contained, with about 250 firefighters and several air-tankers and helicopters assigned to the battle in the Ebbs and Wild Goose canyons.

The Major Evans Fire, ignited Sunday by a recreational vehicle explosion, had burned 15 acres of steep oak brush and timber terrain northeast of the Tibble Fork Reservoir. Fire Information Officer Kathy Jo Pollock said about 40 firefighters were battling the flames, located at the junction of Major Evans Gulch and North Fork of American Fork Canyon. It was 85 percent contained Monday night.

Volcanos

Roundup of Global Volcanic Activity

Kliuchevskoi (Kamchatka): The volcano continues to erupt a lava flow that descends on the eastern flank. It also sometimes (such as during much of yesterday) has phases of near-continuous explosions at the summit craters, generating ash plumes that rise up to approx. 1 km from the summit. Today, no significant ash emissions were observed.

Sakurajima (Kyushu, Japan): After more than 3 weeks with no recorded eruption, a strong vulcanian-type explosion occurred this evening at 00:02 past midnight (15:02 UTC). The initial estimate of the ash plume was corrected from 10,000 to 20,000 ft (6 km) altitude, making the event one of the larger ones among Sakurajima’s long list of vulcanian explosions throughout the past years. Whether or not the volcano will return to a more regular style of explosive activity remains to be seen.

Suwanose-jima (Ryukyu Islands): Judging from recent webcam imagery, activity has decreased again at the volcano although the On-take crater continues to produce a significant steam plume and occasional ash emissions, but much less vigorous than earlier this month. Only week glow if any can be seen at night.

Sinabung (Sumatra, Indonesia): Explosive activity continues. The most recent eruption was reported by PVMBG and VAAC Darwin yesterday at 10:28 local time. It generated an ash column that rose approx. 1500 m above the volcano’s summit.

Popocatépetl (Central Mexico): The activity at the volcano has remained essentially unchanged and been rather low during the past week. On average, CENAPRED recorded 100-200 low-energy emissions (“exhalations”) and few, generally weak explosions with ash emissions, accompanied by intermittent phases of weak tremor. Glow at the volcano’s summit at night indicates the continued slow growth of a lava dome inside the inner crater.

Fuego (Guatemala): A small lava flow is descending on the upper SE flank into the Santa Teresa drainage, generating near-constant small glowing avalanches. Explosive strombolian activity is relatively week at the moment; the volcano observatory counted 20 explosions for the past 24 hours, generating ash plums that rose up to approx. 500 m and drifted 10-12 km S and SW before dissipating. Many of them were accompanied by shock waves and jet-engine like degassing sounds that lasted up to 2 minutes. Incandescent bombs were seen to reach to 150-200 m height above the crater.

Turrialba (Costa Rica): A series of eruptions has been occurring from the volcano’s active western crater during the night and this morning and is likely still going on. Costa Rican volcanologist describe the explosions which each lasted a few minutes as phreatic, i.e. driven by overheated water from the hydrothermal system suddenly flashing into steam. The first explosions occurred at 21:22 and 22:16 local time last night and were followed by similar ones at 07:22 and 08:25 this morning. The eruptions were similar to many others in the ongoing phase of intermittent explosions at the volcano during the past months; they ejected ballistic blocks of high temperature to the crater rim and generated ash plumes that rose several hundreds of meters before drifting SW where ash fall occurred in nearby areas.

Nevado del Ruiz (Colombia): The Manizales volcano observatory reported a small ash emission yesterday afternoon, but cloud cover prevented detailed observations.
